Radiocarbon dating can easily establish that humans have been on the earth for over twenty thousand years, at least twice as long as creationists are willing to allow. They have their work cut out for them, however, because radiocarbon (C-14) dating is one of the most reliable of all the radiometric dating methods.
Is carbon dating truly accurate?
This carbon comprises a steady ratio of Carbon-12 and Carbon-14. Advancing technology has allowed radiocarbon dating to become accurate to within just a few decades in many cases. Carbon dating is a brilliant way for archaeologists to take advantage of the natural ways that atoms decay.
What are the limitations of carbon dating?
The method has limitations: Samples can be contaminated by other carbon-containing materials, like the soil that surrounds some bones or labels that contain animal-based glue. Inorganic materials cant be dated using radiocarbon analysis, and the method can be prohibitively expensive.
